SPECIFICATION forming part of Letters Patent No. 430,776, dated J une 24, 1890.

Application filed February 10, 1890. Serial No. 339,771. (No model.)

To all whom it may concern:

Be it known that I, EMERY M. HAMILTON, of the city, county, and State of New York, a citizen of the United States, have invented certain new and useful Improvements in'lypelVriting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a type-writing machine of the class commonly known as typebar machines, in which the printing-type is carried by a vibratory type-bar, and in which the type-bars are arranged radially in a eircular series andvhave a common printingpoint at the center of the series, and also in which the type-bars are operated by key-levers arranged in a series in the machine, usually in a plane below that of the type-bar circle and substantially parallel therewith, and severally connected to the respective typebars by links or rods, whereby the series of key-levers occupies an area in the machine which is greater than that of the type-bar eircle and extends laterally in the machine, so that some of the key-levers lie 'beyond the circumference ofthe type-bar circle on oppoi site sides thereof.

The principal object of my invention is to reduce the distance necessary, as above set forth, in machines of the class stated, between the type-bar circle and the series of key-levers, and thus to lessen the height or equivalent dimension of the machine, and, furthermore, to permit the type-bar circle to be contracted in its circumference or area, thus promoting compactness of structure.

My invention consists, primarily, in the combination, in a type-writing machine having a circular series of radially-arranged vibratory type-bars and a series of key-levers fulerumed at one side, and preferably at the rear, of said circular type-bar series, of an auxiliary lever fulcrumed outside of the circular type-bar series and intersecting and at such intersection pivotally connected to certain of the key-levers, and a link or rod connecting said auxiliary lever to certain of the type-bars in the segment of the circular series thereof which is adjacent to the key-lever fulcrums, whereby said link or rod connecting the auxiliary lever to its said certain Ysingle key-lever and auxiliary lever.

type-bar may be arranged relatively to said auxiliary lever substantially at right angles thereto, as and for the purpose hereinafter set forth; and my invention also comprises the combination, in a type-writing machine, of devices, hereinafter particularly described, by which movement or feed is imparted to the spools or bobbins of the inking-ribbon.

ln the drawings, Figure l is a plan of a typevrit-ing machine containing my invention. Fig. 2 is a similar View of the same, the paper-carriage and top plate of the machine being removed and a portion of the type-bar ring cut away to disclose' the keylevers, auxiliarylevers, and connecting-links arranged according to my invention. Fig. 3 s a vertical section of the machine, taken on line x m, Fig. l, looking toward the rearward end of the machine, the paper-carriage and type-bars being removed, and showing a Fig. fl is a vertical section of the machine, taken on line y y, Fig. l, and at right angles to the Section shown in Fig. 3, and showing two type-bars and a portion of the key-levers and auxiliary levers. Fig. 5 is a plan in detail illustrating two trains of levers and their type-bars, one of said trains including an auxiliary lever; and Fig. 6 is a vertical section in detail on line .c e, Fig. 5, illustrating said two lever-trains and the type-bars actuated thereby.

In Figs. l, 3, and 4 the devices constituting the inking-ribbon movement are illustrated.

The machine shown in the drawings comprises certain novel devices by means of which the type-bars are pivoted and supported in their series, the paper-carriage is moved, the platen carried by the carriage is given the usual motions and holds the paper for printing, and the spacing-key is mounted and arranged. A description of these several novel devices is not necessaryherein, as they constitute no part of the invention covered thereby; but they are reserved lierefrom and made the subj ect-matter of otherseveral applications for Letters Patent by me, to wit: Serial No. 330,766, relating to the typebar fulcrums; Serial No. 339,767, relating to the paper-carriage, and Serial No. '3239,770, relating to the spacing-key, filed simultaneously IOO herewith, and Serial No. 343,108, relating to the support and arrangement of the typebars in their series, filed March 8, l 890.

AtA is represented a series of type-bars arranged radially in a circle and fulcrumed to brackets in a holding-ring A. The typebars are all usually fulcrumed in the same plane and strike or print at a common printing-point, which is at the center of the typebar circle.

At B is represented a series of key-levers, usually and preferably arranged in the machine, as shown, below and in a plane parallel to the plane of the type-bar circle, so as to extend laterally horizontally of the machine. The key-levers are pivoted or fulcrumed in the machine at or beyond one of the sides of the type-bar circle, and preferably to the rearward side thereof, and extend forwardly below the said circle to the front of the machine, where they are severally provided with iinger-keys B, constituting the customary key-board. rlhe key-levers may be fulcrumed on any of the four sides of the type-bar circle without variation from the essential features of my invention. In arranging these key-levers I ind it desirable to assemble the rearward or fulcrum ends closely together, as shown in Fig. 2, and to fulcrum them all on a single bar B2, carried by brackets B3, secured to and depending; from a top plate B, upon which plate the various part-s of the machine are mounted, as hereinafter set forth. A shoulder bg is preferably provided'on the end of each lever at its under edge, as shown, adapted to seat to the under face of the fulcrum-bar B2, as shown in Fig. 4, and a spring b3, seated by an angularlybent end or heel, as shown,in the bar B2, may extend thence to and beneath each of the key-levers and be furnished with an angular bifurcated opposite end or projection b4,

adapted to engage the under edge of the lever. This fulcrum mounting of the keylevers is structurally economical, and possesses simplicity, effectiveness, and durability, the arrangement of the shoulder b2 on the lower edgeof each lever, by which the levers are seated to the bar B2, adapting the levers formed of flat metal strips or bars to the strain thereon when they are moved or vibrated on their respective fulcrums, and gives the described levers an increased rigidity vduring vibration. The assembling of the levers is likewise simplied by the described arrangement, as they may be readily seated to the bar B2, and the springs b3 quickly engaged by slightly iexing them and springing the end b4 of each over the edge of its respective lever. In moving thelevers they vibrate against the stress of the springs respectively in operating the type-bars, and upon being released are returned to their normal positions by the recoil of the springs respectively.-

From their closely-assembled fulcrums, as described, the key-levers extend forward in resents one of those key-levers B which lie or pass beyond the edge of such circle. In carrying out the primary feature of my invention I employ an auxiliary lever C, fulcrumed or pivoted outside of the type-bar circle and preferably, as shown, at one end to a bracket BG, which is desirably securedr to and depends from the top plate B, so that said auxiliary lever will extend laterally of the machine and to and across and preferably above the key-lever D', to which it is pivotally connected at its intersection therewith, desirably by a link c. rlhe auxiliary lever C extends to a point in line directly below a type-bar in the segment of the circular series thereof which is adjacent to the key-lever fulcrums, and is there pivotally connected to said type-bar by a link er rod D, which link or rodmay be arranged relatively to said auxiliary lever substantially at right angles thereto, as shown. It is obvious that I am enabled by means of these described devices to construct a machine in which the type-bar circle may be made of such diameter only as will accommodate the fulcrums or journalbearings of the type-bars, with the radial type-bars themselves of such a length only as will enable them to strike at a common printing-point at the center of the circle, and that the key-levers may be arranged or located immediately below and close to the pendent ends of the type-bars when the latter are in a position of rest, and that by an auxiliary lever C, pivotally connected to certain of the key-levers b, lying beyond the circumference of the contracted type-bar circle, and a link D, arranged at right angles to said auxiliary lever, as described, and connecting the same to a type-bar in the rear segment of the circular type-bar series, I may, by a depression of the key-lever b at its finger-key, obtain the sum of the vibrations of the said key-lever and auxiliary lever in a direct vertical pull through the link D on the type-bar, so that while structural compactness in the machine is promoted the actuating-lever movement is communicated to the type-bar from a lever lying beyond the type-bar circle in the most eifective manner.

It is apparent that in a machine thus constructed a key-lever b passing under the typebar circle may be connected directly to a type-bar in the front segment of the circular type-bar series, in line with it above it, by a link D', arranged at. right angles to the keylever, as shown in Figs. 4, 5, and 6, and it is IOL ISO

also evident that an auxiliary lever C maybe so proportioned and arranged to intersect and be pivotally connected to a key-lever h lying beyond the type-bar circle at such a point relatively to the fulcrums of each of said levers that the sum of the length-of the auxiliary lever from its fulcrum to its joint with the link D uniting it to a type-bar in the rear segment of the circular type-bar series and of the key-lever b from its fulcrnm to its joint with the said auxiliary lever will be substantially equal to the length of the keylever Z) from its fulcrum to its joint with its link D uniting said lever?) directly to a typebar in the front segment of the circular typebar series, whereby the sum of the vibrations of the key-lever b and its auxiliary lever, by a depression of said key-lever h at its Yfingerkey, will be substantially the same as the vibrations of the key-lever l) by a substantially equal depression thereof at its finger-key, so that an equal movement of the key of a lever lying under the type-bar circle and of the key of a lever lying beyond such circle will effect an equal extent of' vibration of their respective type-bars in printing.

ln constructing a type-writing machine containing my invention I employ a series of auxiliary levers C, as shown in Fig. 2, in two sections or divisions corresponding to the groups of the key-levers which lie beyond the type-bar circle or opposite edges thereof. ln Fig. 2 one of these sectionsor. divisions of the series is fully shown, and it will be understood that the opposite section (partly shown) is similar thereto in all respects. The auxiliary levers C of each section are desirably all pivote/d or fulcrumed at one end to a common rod or pin set in a bracket B, which, as stated, is secured to the top plate B4, and depends therefrom. rlhe said auxiliary levers are preferably severally controlled by retracting` springs c', similar in form and application to the springs b3 of the key-levers, heretofore described. These levers C extend laterally in the machine, and preferably in substantially parallel lines across and immediately above those of the key-levers-namely, bwhicl1 lie beyond the type-bar circle and reach respectively to type-bars in the segment thereof which is on the side adjacent to the k ey-lever fulcrums-that is to say, to the segment of type-bars which is to the rearward of the machine.

rlhe levers C preferablyterminate, respectively, at points in line below their several type-bars in such segment, and they are severally pivotally connected, as by short links c, to key-levers D at their intersection therewith, and at their ends which are opposite to their fulcrums are connected to their' respective type-bars in`the rear segment of the circular type-bar series by links D, which links may be arranged relatively to their respective auxiliary-levers at a right angle thereto, as shown. The key-levers h of the series thereof which pass under the type-bar circle are connected, respectively, to type-bars in the segmenton the the front side of the machine by links D', which may be arranged at right angles to their key-levers. I find this arrangement preferable, for the reason that the length of the levers l), respectively, from their fulcrums to the type-bars in the front segment obviously adapts them to be connected to their type-bars by links D which are rectangular to the key-levers, and to thereby impart an effective movement to-the type-bars through said links, while the distance between the fnlcrunis of the key-levers h', respectively, which lie beyond the type-bar circle, and points in line with type-bars in the rear segment thereof, being comparatively small, the auxiliary levers C can be effectively combined with such key-levers h in not only obtaining a direct vertical pull on the links D, but also in multiplying the lever movement between the finger-keys and the type-bars. In arranging the auxiliary levers C of each division of the series thereof I therefore so proportion the length of cach auxiliary lever and link it to a key-lever h at such a distance from the fulcrum of its key-lever that the sum of the total length of each auxiliary lever and the length of its key-lever from its fulcrum to its joint with the auxiliary lever shall be approximately the same in all the key-levers and auxiliary levers of the combined series thereof, whereby substantially the same vibration or depression of all the key-levers h at their key ends will effect a substantially equal vibration of the auxiliary levers at their joints with their respective links D, and consequently a substantially equal movement of all their respective type-bars in the rear segment of the type-bar circle in printing. And, furthermore, it will be understood that in thus arranging the levers b and C the said levers are so proportioned, f ulcru med, and united to each other, respectively, and to their links D, as recited, relatively to the proportions and arrangement, respect-ively, of the k ey-levers Z) and their links D, connected to the type-bars in the front segmentof the type-bar circle, as hereinbefore set forth, that a substantially similar movement or depression at their iinger-keys of any of the key-leversband b will effect a substantially similar movement of the links D or D', as the case may be, and consequently a substantially like oscillation of all the type-bars of the series thereof.

By arranging the key-levers, fulerumed as set forth,- at the rear side of the type-bar circle closely adjacent to the ends of l the typebars when said type-bars are normally pendent in the machine, and by arranging the auxiliary levers fulcrumed outside of the type- IOO IIO

bar circle immediately above the key-levers and intersecting the same, as described, I am enabled to connect all the type-bars to their actuating-levers by links which are substantially rectangular to said levers7 and to have the links connecting the type-bars in the rear segment of the type-bar circle to their respective auxiliary levers of a less length than the links connecting the type-bars in the front segment of the type-bar circle directly to their respective key-levers, thereby promoting coinpactness of structure in the machine.

In the machine shown motion is given to thecarriage-actuating mechanism by means of a lever E, which is pivotally hung at e in the hangers or frame B3, Figs. 3 and 4, an arm e of said lever reaching to and engaging the carriage-actuatin mechanism, while the arm e2 is engaged by all the key-levers, as by means of a bar es, linked to said arm e2 and hanging below and against the under faces of the key-levers. The depression of anyof the key-levers rocks the lever E, thus vibrating its arm e. This lever is commonly called the universal lever in type-writing machines, and its function and operation are well known.

It should be noted that in promoting structural compactness in the machine a base-plate or standard is dispensed with, and that a top plate B2,with the hangers B3, carrying the bar B2, and the fulcrum-brackets B, secured `to said top plate, serve as the supporting-frame, upon which the several working parts of the machine are fastened. The plate B4 may serve as a lid or cover to a case or box B7 inclosing the levers and type-bars, as shown. The type-bar ring A may be secured to the plate B, and a supplemental plate B8, perforated to accommodate the passage and play of the iinger-keys B, may extend from or be secured to the forward edge of said top plate.

At l" and F are shown the inking-ribbon spools carrying the usual inking-ribbon R, said spools having respectively the shafts f f', having bearings in the machine-frame, as shown. These shafts are arranged horizontally on the machine, and are provided with the ratchet-wheels f2 f3, respectively.

G and G are bell-crank levers fulcrurned, respectively, at g and g', with an arm g2 of each pivotally connected, preferably by a pin g3, common to both said arms, to a rod g4, which is reciprocated by the arm e of the universal lever. Each said bell-crank lever has a pawl-like arm g5 arranged and located in the machine at a right angle to the plane of its respective ratchet on the spool-shafts and reaching to and adapted to engage the periphery of said ratchet tlatwise of said pawlarm, as shown.

H is a bar carrying or provided with projections h, having, respectively, oppositely-inclined faces 7L', said projections being located on said bar relatively to said pawl-arms g5, so that when one of said projections engages one ot said pawl-arms by its inclined face the other projection is free from engagement with the other pawl-arm, as shown. II has longitudinal movement on suitable guides h2, so that either projection may be engaged to the corresponding pawl-arm. The

The bar pawl-arms are flexible or adapted to have play latwise at their fulerums, whereby when the bar II is moved to bring either one of its projections into engagement with the corresponding pawl-arln, said. pawl-arm will be thereby lifted out of engagement with its ratchet, the other pawl-arm being by the same movement of the bar released from the other projection, and hence free to engage its ratchet. The reciprocation of the rod g4 operates to cscillate both the levers G and G continuously, and the respective pawl-arms g5 of said levers, by engagement with the ratchets f2 f3 alternately, respectively, thereby operate to rotate the ribbon-spools in either direction, as desired, at each vibration of the universal lever during the operation of printing.

The form and arrangement given to the levers G G and their pawl-arms g5 and the l0- cation of the latter, as described, relatively to the in king-spool ratchet-namely, at right angles iiatwise to the planes of the respective ratchets enables the mechanism which actuates the hiking-spools to be given compactness of structure and to occupy but a very limited space in the organization of the machine.
